An ostrich breeding flock, joined as individual breeding pairs (n = 136 pairs), was used to investigate the possibility of diagnostic ultrasonography as a method to predict the reproductive performance of ostrich females during a breeding season. Follicular activity was easily detected and quantified by using diagnostic ultrasonography. One to 8 follicles were recorded in 25% of females scanned...

Ovarian follicle selection is an important process impacting the laying performance and fecundity of hens, and is regulated by follicle-stimulating hormone (FSH) through binding to its receptor [follicle-stimulating hormone receptor (FSHR)]. In laying hens, the small yellow follicle (6-8 mm in diameter) with the highest expression of FSHR will be recruited into the preovulatory hierarchy during...

the aim of this study was to evaluate the defense cells changes of cervical mucous during follicular and luteal phases of estrus cycle in river buffalo. reproductive organs of the adult and apparently healthy female buffaloes were collected from the slaughterhouse. by visual investigation of both the ovaries for presence of corpus luteum and growing follicles, the luteal and follicular phase of...

Adenomatoid odontogenic tumor (AOT) is an uncommon, slow-growing, noninvasive mostly in the anterior maxilla with three well-recognized clinico-pathological variants: follicular, extra-follicular, and peripheral. Extra-follicular variant presents as a well-defined, unilocular, radiolucency between, above, or superimposed on roots of erupted tooth. A 19 years female reported chief complaint loos...

A unique 'second' niche for follicular B cells has been described in the extravascular compartment of the bone marrow surrounding vascular sinusoids. The occupancy of this niche by B cells presumably evolved to facilitate humoral immune responses to blood-borne pathogens. B cells appear to be sustained in this niche by bone marrow dendritic cells and are lost from this compartment in certain mu...

Developing B cells undergo selection at multiple checkpoints to eliminate autoreactive clones. We analyzed B cell kinetics in the NOD mouse to establish whether these checkpoints are intact. Our results show that although bone marrow production is normal in NOD mice, transitional (TR) B cell production collapses at 3 wk of age, reflecting a lack of successful immature B cell migration to the pe...

BACKGROUND Enhanced vascularization appears to be important for follicular selection and maturation in both spontaneous and stimulated IVF cycles. Nitric oxide, formed in vivo from L-arginine, may play a key role in follicular maturation and ovulation. METHODS To evaluate the role of L-arginine supplementation in controlled ovarian hyperstimulation, 37 IVF patients were divided into two group...
